What about the shading?? NNnnnghh

You forgot the violent smashing of your head on the keyboard.

CAnt puzzle out if there is a subtle difference between colour and final animation or not.

You could make this into a tutorial, and a lot of people could learn from this. Some "animations" have very little animation in them. The theme could be, "This is animation, this is NOT animation," and have examples of good animation like this one, and bad tween/jumpy/geometric/morphing stuff that come thru. A tutorial like that could help, but could also be really fun. :)
